And when Philadelphia students order their meals on the web, they're more likely than most to ask for special preparation requests, a new GrubHub analysis finds. The online-ordering site says it analyzed a year's worth of order data from more than 350 campuses to see which schools had the pickiest eaters.

But, those picky Philly students are at least polite: Several Philadelphia schools also ranked among the most likely to include "please" and "thank you" in the special instructions.

Here's the top 10 schools in the two categories, according to GrubHub's analysis.
